Figure 48. Programmable Sequence Flowchart
The AD7329 can be configured to automatically cycle through
a number of selected channels using the on-chip sequence
register with the Seq1 bit and the Seq2 bit in the control register.
Figure 48 shows how to program the AD7329 register to
operate in sequence mode.
After power-up, the four on-chip registers contain default
values. Each analog input has a default input range of ±10 V. If
different analog input ranges are required, a write to the range
registers is necessary. This is shown in the first two serial
transfers of Figure 48.
These two initial serial transfers are only necessary if input
ranges other than the default ranges are required. After the
analog input ranges are configured, a write to the sequence
register is necessary to select the channels to be included in the
sequence. Once the channels for the sequence have been
selected, the sequence can be initiated by writing to the control
register and setting Seq1 to 0 and Seq2 to 1. The AD7329
continues to convert the selected sequence without interruption
provided that the sequence register remains unchanged and
Seq1 = 0 and Seq2 = 1 in the control register.
